Early Summer Interests at the Washington Park Arboretum

Roy Farrow
1) Corylus colurna Turkish Hazelnut or Filbert
- The Turkish Hazelnut is native to southeastern Europe into western Asia.
- In summer, edible nuts are produced inside dramatically styled husks.
- The Turkish Filbert can be found along Foster Island Road, opposite the Broadmoor gatehouse.
2) Hydrangea macrophylla ‘Sumida-no-hanabi’ Bigleaf Hydrangea
- ‘Sumida-no-hanabi’ translates to “fireworks over the Hanabi River”.
- This wonderful hydrangea can be found in the Centennial Garden along Azalea Way.
3) Magnolia grandiflora Southern Magnolia
- Stunning flowers in both beauty and scent are produced in mid-summer from these statuesque evergreen trees.
- Though native to the southeastern U.S., certain selections of M. grandiflora are hardy to zones 5b, or around -15 degrees F.
4) Picea smithiana West Himalayan Spruce
- Also known as the Morinda Spruce, this tree can grow to over 200 feet in its native range.
- The needles of Picea smithiana are among the longest of the genus.
- Specimens of Picea smithiana can be found on the Sino-Himalayan hillside and along the Arboretum’s eastern fence line in our Sorbus Collection.
5) Poliothyrsis sinensis Chinese Pearlbloom
- The fragrant, white flower buds of Poliothysis open only slightly, retaining a spherical shape, thus the common name of Pearlbloom.
- A fine specimen of Poliothysis resides in the Woodland Garden along Arboretum Drive.
